HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 752,193, dated February 16, 1904.

Application filed April 7, 1903. Serial No. 151,533. (No model.)

To (ZZZ whom it mag/ concern:

Be it known that I, EDGAR B. BADLAM, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Hydrocarbon-Burners; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in apparatus for the combustion of liquid hydrocarbons.

It consists in an apparatus by which the temperature of the fluid is gradually raised during its progress from the point of admission to a point where it is finally subjected to the highest degree of heat just before being delivered to the burner-injector in the form of a dry highly-heated gas.

My invention also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in.whichi Figure 1 is a vertical section of the apparatus. Fig. 2- is a plan, apart of the distributor. My apparatus is especially designed for the combustion of liquid hydrocarbons of anyvdescriptionsuch as gasolene, naphtha, coal-oil, &c.so as to vaporize and burn them without the formation of carbon deposit in retort or coils. In order to effect this result, the liq' uid hydrocarbon should not be vaporized in long uniformly -heated coils or in spacious heated retorts, the inlets or outlets of which are virtually of the same degreeof heat.

In my invention, A is a central chamber of any desired size and shape. In the present case I have shown it vertically disposed, and the apparatus as here constructed is very suitable for heating boilers for engine-propelled vehicles or for any similar or other purpose.

2 is an inlet tube or passage, and 3 is a nee-. dle valve or jet through which the gas is discharged into the tube 2, and thence directed into the central vertical tubular chamber A. The liquid from which the gas is produced is admitted through. a suitable valve 4: into a pipe 5. This'pipe extends upward alongside and at a suitable distance away from the central combining chamber A, thence it coils around the outside of said chamber a sufiicient number of turns, as shown at 6. i In the present case I have shown the upper part of the chamber. expanded into a pan A of considerable diameter, around which the coils 6 are part of thechamber so as to more intensely heat the upper part'of the coil and to also direct the heat against the part to which it is to be ultimately applied. This distributor is adjustable up or down to suit the character of the hydrocarbon used, or the coils might be movable and the distributer stationary. As here shown, this distributer consists of radially-disposed vanes, which are bent more or less, like the blades of a propeller-fan or windmill,as at 8. The gas, ready for combustion, rising through the chamber A A", strikes these vanes and is diverted upwardly and outwardly in such a manner that when ignited an intense heat is directed upon the uppermost member of the coil. The gas also passes through between the vanes and upwardly against the part to be heated in spiral or vortex-like manner or vertically, if so desired.

. 9 is a gauze screen through which the gas passes before ignition and which maybe placed either below or above the distributer. The form of the distributer and the angle at which the vanes stand are well shown, and their position relative to the gauze screen will depend upon the character of the hydrocarbon which is used, as gasolene or coal-oil, and the mannor of distributing the fire that may be desired. The operation of this part will then be as follows: The hydrocarbon having been admitted through the valve 4, previously described, passes through the pipe and into the first lower portion of the coil. The coil, having been previously heated by a pilot-light or apreliminaryheating-pan, will be'sufiiciently warm to partially vaporizethe liquid and produce sufiicient gas to commence operations. The apparatus being heated, the radiant heat IOO 7 rounding the tube.

therefrom will first act upon the lower portion of the coil and raise the temperature of the liquid, eventually changing it into vapor, and as it passes around the coil it will be in condition when it reaches the upper turns of In order to first commence the operation, I have shown a pan 1O fixed below the coil and sur- In the bottom of this pan may be fixed any fibrous or absorbent material, such as asbestos, and a portion of inflammable liquid having been placed therein and ignited the heat will be sufficient to raise the temperature of the coil for the preliminary operation. Through this annular pan air-tubes 11 pass and provide suflicient air for combustion. Above the pan I have shown a pilot-burner 12, which is curved around beneath the coils, and a pipe 12, connecting with this burner, is adapted to receive a portion of the gas from the coil through a branch pipe, as at 13. The passage from these pipes is controlled by a valve, as at 14:, and when the main fire is not in use a small pilot-fire can be maintained by means of this device which will maintain a sufiicient heat in the coil to'be in readiness for operation whenever the main burner is to be again operated. The burner proper is operative practically without the pilot-burner.

The distributer 8 is here shown as having a central support, as at 15. This support may be a rod; but I have here shown it as a hollow tube open at the bottom to admit air or an inflammable vapor or gas which may be admitted, so as to pass up through and be ignited at the top, as before described.

16 is a pipe to drain ofi any liquid which may collect within the chamber A.

In the drawings two methods are shown for adjusting the distributer vertically. One of these methods includes the turning of a plug 30, which screws into the bottom of the chamber A and carries the tube 15, whereby when the plug is screwed up or down the distributer is moved and its position adjusted. The second method includes the use of the nuts 32 at the top of the tube 15 and between which the distributer-vanes are clamped. Ordinarily when the apparatus is first set up the position of the distributer with relation to the screwplug '30 at the bottom of the chamber will be determined by means of said nuts. After that any adjustment may be made, by moving the screw-plug at the bottom.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A hydrocarbon-burner consisting of a central combining-chamber, a coil surrounding the upper part thereof, means for admitting the hydrocarbon into the lower part of the coil, means for delivering the gas through a jet into the said chamber, and a device including a disk having radial peripheral vanes whereby the gas ignited at the upper part of the chamber is directed against the upper part of the coil.
